I own a Panasonic FZ35 for a few years. Recently I bought a Sony NEX-5T, since I noticed the sensor used in NEX-5T is about 10 times large as the sensor used by FZ35. I tried to compare two cameras. I tried low lights, near distance, far distance, etc. Most time I used a tripod with 2 or 10 seconds delay so that there was no hand movement involved. I tried automatic, P, A, S, M options. I was surprised that there were no noticeable differences between two sets of pictures. I even showed my co-workers those two picture sets (blindly). They also said the difference was minimal. Anybody here can help me how should I compare those two cameras, or just tell me the sensor size does not really matters and why. Thanks.
